HEELING-MACHINE.

Specification of Letters Patent.

Patented Jan. 18, 1921.

To aZZ whom it may concern:

Be it known that I, JOHN F. STANDISH, a citizen of the United States, residing at VVinthrop, in the county of Suffolk and Stateof Massachusetts, have invented certain Improvements in Heeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to heeling machines and, more particularly, to the equipment of such. machines with provision for attaching rubber, or other cushion, heels.

In attaching a cushion heel in a heeling machine, where the heel is necessarily subjected to a considerable degree of pressure, it is desirable that the heel be held in a rigidly immovable holder or form of considerable depth, to prevent distortion of the heel by the pressure and movement of the nail holes in the heel out of register with the holes in the nailing die through which the attaching nails are driven into the heel. Rubber heels, however, are usually of only moderate height and, inasmuch as the heads of the attaching nails are driven deeply into the heels, the nails used for this work are short. The presence, therefore, of a deep heel form upon the nailing die prevents a sufficiently close approach of the loader block, which delivers the nails to the die, to insure that these short nails shall enter the holes in thedie.

One object of the present invention is to overcome the difliculty above outlined and, with this end in view, a feature of the invention consists in the combination with a nailing die and a loader block movable over and in close proximity to the die, of a rigid heel holder movable from an initial position over the die to a position at one side of the die, to permit the loader block to be moved into the space initially occupied by the holder. In order to permit both the loader block and the heel holder to occupy, alternately, a position over, and close to theupper surface of, the die, they may'conveniently be arranged to move in substantially the same plane, the holder being in the path of movement of the loader block into nail delivering position, whereby the loader block, in its movement into such position, will engage the holder and push it to one side, out of register with the die, Suitable means such, for example, as a spring, may be provided to return the holder to heel attachin posi- -ti on after the loader block is retracte holder to shift whenthe attaching pressure is applied. In this aspect of the invention, another feature thereof resides in the provision, in a heeling machine having a movable heel form or holder, of a locking member so directly connecting the holder to a relatively fixed portion of the machine that it immovably held in heel attaching position. The locking means is preferably arranged to release the holder automatically under the control of the loading mechanism at the proper time to permit the holder to be moved away from attaching position. In the embodiment of the invention hereinafter" described, an elemenet of the locking mecha nism is located in the path of the loader block, and is automatically actuated to release the form prior to the engagement of the latter by the block.

It is frequently desired to use the same machine, at will, for attaching either rubber or leather heels. In this connection, another feature of the invention consists in the provision of a specialholderlmovable during the operation of the machine, which may be used in rubber heel attaching, constructed to permit easy, and instant removal, without the use of tools, whereupon the regular holder for leather heels may be placed upon the machine for use in the ordinary manner.

The invention further provides a heel holder normally occupying a heel attaching position upon the nailing die, but arranged to be moved away from the die and locked in a position where it will not interfere with the changing of dies for different nailings. After the change of dies has been made it is simply necessary to withdraw a locking pin to permit the holder to resume its operative position. This feature may be advantageously combined with a holder consisting of a form carrier constructed to accommodate any one of a series of removable and interchangeable form members fitting heels of difierent sizes and shapes. The locking pin may advantageously cooperate with a stationary stop which serves the double function of securing the holder in position away from the die while dies are being changed and limiting the movement of the holder away from the die, under the impulse of the loader block in ordinary operation.

These and other features of the invention will best be understood and appreciated by reading the following detailed description in connection with the accompanying drawings illustrating, one embodiment thereof though it should be understood that various features of the invention might be embodied in other specific forms of construction without departing from its spirit and intent.

The term loader block is used throughout the specification and claims in a generic sense, to denote any suitable form of device for carrying a load of nails to, and depositing them in, the nailing die.

In the drawings,

Figure 1 is a perspective view of one embodiment of the invention as seen from the front and left;

Fig. 2 is a similar view irom the rear and left;

Fig. 3 is a similar view from the front and right;

Fig. 4: is a vertical, longitudinal section from front to rear; and

Fig. 5 is a perspective view of a detail oi the locking mechanism for the holder.

Referring now to the drawings, 10 indicates the driver head and 12 the nail drivers of a heeling machine; and l-l indicates a pair of side rods carrying the mailing die supporting member 16. The general con.- struction and arrangement of these parts substantially the same as in the machine disclosed in Patent No. 1,1574388. granted Oct. 26, 1915, upon the application of L. L. Glidden, to which patent reference may be had for a full disclosure of the construction and operation of those features of a heeling machine with which the present invention is not concerned.

The nailing die, through which the drivers 12 pass to drive the heel attaching nails, is shown at 18. In accordance with the usual practice, the nailing die is made of a standard size and is readily removable from the support 16 by simply turning up the buttons 20 and drawing the die forwardly out of its seat in the support. Other standard or interchangeable dies may thus be easily substituted to produce a nailing of any desired size or shape.

The rear portion of the nailing die sup port 16 is bored out to receive the reduced end 22 of a cylindrical guide bar 24, which is supported rigidly in a horizontal position in a suitably formed trough or groove 26 extending along rear of the die support.

28 indicates a heel iorm carrier having a rearwardly extending portion 30 which is bored out to lit. bnt slide tireely upon. the guide bar 24:. One end oi a tension spring 32 anchored upon a pin 34 inserted in a bracket 31' extending from the side oi the die support 16. The opposite end oi the spring is secured in a lugiltl projecting i'rom the iorm carrier. This spring}? always under tension and tends to draw the i'orm carrier toward the right. as seen in Figs. 1 and 3, normally holding: ii with the end of the member 30 in engagement with an adjustable stop 40 secured by a bolt and slot connection to the portion "12 oi the nailing die support 16.

The form carrier is provided with guides in which may be removably secured a heel form member 41st oi? considerable depth and shaped to lit the heel to be attached. An interchangeable series oi these form members is provided to accommodate all the di ilereni sizes and shapes of heels to he handled. The form member is secured in position in the carrier 28 by a pin 4:6. which is norimilly held in securing}; position by a spring i9 bui which may be readily withdrawn to permit the changing of forms. d hcu the term member 44- secured in the carrier 28 and the stop 40 properly adjusted. the heel holder, comprising the ioriu carrier and form member, will normally occupy a position immediately over the nailing)! die lo. in which the nail holes in the rubber heel 5 1 will register with the holes in the nailing die as clearly shown in Fig. 11-.

In order to insure the heel i'orm agraiusi any possibility of displacement when pressure is applied to the heel. means is provided for looking it ininuivably in heel attaching; position. A latch carried by the lower en oi an upright shai't I l journaled in a su table hearing in the form carrier. is arranged to engage a pin 56 mounied in a longitudinally adjustable plate secured by a screw and slot connection to the die support 16. After adjusting the stop 40 to locate the heel Form in precisely the right position the pin Si) is adjusted to engage the hook ot' the loclriiiggts member upon the form carrier. The hoolr is held in engagement with the pin 56 by a iorsion spring" ()0 surrounding the shaft 51. one end of the spring bears against the flange 69. which is part of the Form carrier. and the other end is bent around an arm (ll secured to the upper end of the shait 54-. ly swiu inp; the arm 64 in a clockwise direction the spring 60 will be caused to yield and the latch 52 will be i'novcd out oi locking! engagement with the pin 56. permitting the form carrier to be moved toward the left against the tension of the spring 32.

The tront end of the iorm carrier extends downwardly :in front of the nailing,

lilil lll die and die support, as shown at 66. A slot 68 is formed in the inner face of the exten sion 66 and is properly located to engage a roll 70 rotatably mounted upon a stud 72 secured in the nailing die support 16 by a set screw 74. The end of the slot 68 is curved upwardly at 76' The slot 68 in the extension 66 and the roll '70 constitute guiding bearings for the front of the form carrier, which is guided at the rear by the bar 24. Inasmuch as the guide bar 24 is cylindrical, the form carrier may have both a longitudinal sliding movement and a swinging movement about the axis of the bar. This swinging movement is effected by the curved portion 76 of the slot 68, and its purpose is to force the form carrier down closely upon the die when the form is in heel attaching position, but to cause it to be raised slightly from the upper face of the die and die support as it is moved away from heel attaching position, thus avoiding friction and possible interference with the movement of the holder by dirt, which frequently accumulates on the top of the die and die support.

The nails are supplied to the nailing die prior to the heel attaching operation by the loader block 80, which is mounted to swing about the vertical stud 82 and moves in substantially the same plane as the heel. holder, that is to say, as close as possible to the top of the nailing die and its support. It is important that the loader block approach as closely as possible to the surface of the nailing die. since the nails used for attach-- in g rubber heels are usually quite short and must be guided practically continuously while they are being delivered from the loader block to the nailing die.

A flattened portion 84 upon the end of the arm 64 of the locking device is arranged in the path of the loader block 80. As the loader block is swung toward the nailing die, it engages first the said flattened member 84, swinging the latch 52 out of engagement with the pin 56 and unlocking the heel holder. Further movement of the loader block causes the flattened member 84 to engage a suitably formed and located lug 86 projecting from the flange 62, transmitting the motion of the loader block to the form carrier, which slides toward the left away from its normal heel attaching position over the nailing die. After the load. of nails has been delivered to the nailing die, the loader block is retracted, the spring 32 promptly drawing the heel holder back to its normal position over the die. and the hook 52 automatically locking the holder in position ready for the heel attaching operation.

A lug 90, projecting from the upper face of the nailing die support, lies in the path of a pin 92 which slides vertically in a bearing in the form carrier and is normally de pressed by a spring 94. In the normalv operT ation of the machine the face 96 of the lug 9O acts as a stop to prevent the heel holder from moving too far to the left under the impulse imparted to it by the loader block. When it I is desired to change nailing dies, the heel holder may be moved manually to the left, the pin 92 being withdrawn to permit it to pass over the lug and then released, whereupon the pin will engage the opposite face 98 of the lug, securing the holder in a position away from over the die where it will not interfere with the changing of the dies.

An important advantage of the present in vention is the ease with which the heel. holder may be removed from the machine. leaving the machine ready for the reception. of the usual holder for ordinary leather heel work. It is only necessary to slip the end oi the spring 32 ofli the pin 34 and raise the spring pressed pin 92 to allow it to pass the lug 90, whereupon the form carrier with its form member and locking mechanism may easily he slid bodily off the end of the guide bar 24. This operation can be performed in an instant and requires no tools whatever.

Having described my invention, what .l claim as new and desire to secure by Letters Patent of the United States is 1. In a heeling machine, the combination of a nailing die, a loader block movable over, and in close proximity to, the die, and a rigid heel form movable from an initial. position over the die to a position at one side of the die, to permit the loader block to be moved into the space initially occupied by the form.
